Saliva is wonderful—it has powerful chemistry that protects our bodies against viruses and our teeth against bacteria. It buffers teeth against acid that can cause cavities. It is also a lubricant that makes it easier to taste, enjoy, and swallow food. It helps us speak and gives more suction to removable dentures so they stay in place. Dry mouth conditions can cause us to loose this natural protection against cavities and can cause removable dentures to rub and be uncomfortable.
Some people can have a condition where their immune system attacks their saliva glands and they are unable to produce saliva. Some cancer patients who have radiation to the head and neck can have their saliva glands damaged. Furthermore, over 250 medications, some of them very common, have a suppressing effect on the saliva glands causing dry mouth or “Xerostomia”. People that have not been prone to cavities all their life can quickly develop multiple cavities especially on the root surfaces of teeth that have become exposed with age due to gum disease.
Seniors planning on starting a new medication or having cancer radiation treatment to the head and neck area should brush and floss more diligently than ever before. Super concentrated fluoride prescription toothpastes, rinses, and gels worn in mouthguards can strengthen the teeth against cavities. Chewing of sugarless gum to stimulate saliva flow can sometimes help and avoiding frequent sugary snacks is more important than ever.
